Abstract: A waste collection device configured to remove magnetically-sensitive particles from the air includes a main body, a collection mechanism, an air inlet mechanism, an air exhaust mechanism, and a discharge mechanism. The main body includes a cover, an electric controller, a partition, and a cavity. The partition divides the cavity into a first cavity and a second cavity. The collection mechanism includes a plurality of dust deposition portions received in the first and second cavities. Each dust deposition portion is electrically powered and includes a plurality of dust deposition plates. The air inlet mechanism includes a first wind shield coupled to the first cavity and a second wind shield coupled to the second cavity.

Abstract: The present invention is to provide a locking assembly including a joint device and a safety lock mechanism. The joint device includes a first joint component, a second joint component and a button assembly. The second joint component is pivoted to the first joint component. The button assembly is slidably disposed between the first joint component and the second joint component, and the button assembly is for locking a pivotal movement of the first joint component and the second joint component. The safety lock mechanism movably passes through the second joint component to selectively engage with the button assembly, so as to lock the button assembly selectively. Therefore, it increases the operating safety.

Abstract: The present invention relates to a joint mechanism connected to at least two supporting components of a supporting device. The joint mechanism includes a first joint component connected to one of the at least two supporting components, a second joint component connected to the other of the at least two supporting components and pivoted to the first joint component, and a triggering component movably connected to the first joint component for selectively engaging with or separating from the second joint component. The joint mechanism facilitates folding or unfolding the supporting device. The present invention further relates to the supporting device with the joint mechanism.

Abstract: A child stroller and a stand platform assembly thereof are disclosed. The child stroller includes a frame, a brake assembly connected to the frame, two rear wheels connected to the brake assembly, and the stand platform assembly. The stand platform assembly includes a platform connected to a rear cross bar of the frame, and two sidewalls connected to two opposite sides of the platform. When the child stroller is folded, the folded child stroller is capable of being supported by the sidewalls and the rear wheels, which solves the inconvenience in placing a folded conventional stroller.

Abstract: An electronic device includes a control unit, a battery and a charging current setting unit. The control unit is used to detect a DC voltage of a charger, compare the DC voltage with a predetermined charging voltage minimum, and output a current initializing signal and a current increasing signal to the charging current setting unit. The charging current setting unit is used to adjust a charging current according to signals generated by the control unit and output the adjusted charging current to the battery.

Abstract: A crystalline MgO layer is provided in a position facing a discharge cell formed in a discharge space between the front and back substrates. The crystalline MgO layer includes magnesium oxide crystals caused to emit ultraviolet light with a peak wavelength of between 230 nm and 250 nm by the action of ultraviolet light emitted from xenon in a discharge gas. A phosphor layer emits visible light by being excited by the ultraviolet light emitted from the magnesium oxide layer and the ultraviolet light emitted from the discharge gas.
